Show 1878 .] MR. D. G. ELLIOT ON THE GENUS PTILQPUS. 553 Prof. Schlegel (/. ci), and names afterwards given to them by Salvadori. The principal difference between examples from Celebes and Java appears to be that the former have a much narrower throat-mark, which is lemon-yellow washed with orange. 36. PTILOPUS CHRYSORRHOUS. Ptilopus melanocephalus, Wall. Proc. Zool. Soc. 1862, p. 344 ; Schleg. Mus. Pays-B. 1873, p. 29, ex Sula. Lotreron chrysorrhoa, Salvad. Ann. Mus. Civ. Gen. (1875) vol. vii. p. 671. Ptilonopus sulaensis, Briigg. Abhandl. natur. Ver. Brem. 1876. Hab. Sula, Ceram (Bernstein). » This form has the throat-mark as in specimens from Celebes. The black band on the occiput is smaller, and the abdomen orange-yellow. The characters it offers to support its claim to a distinct rank are not very striking; and it may be questioned if it should be really separated from Pt. melanocephalus. 37. PTILOPUS XANTHORRHOUS. Ptilopus melanocephalus, Schleg. Mus. Pays-B. 1873, p. 29, ex Sanghir. Lotreron xanthorrhoa, Salvad. Mus. Civ. Gen. vol. vii. (1875) p. 670. Ptilinopus nuchalis, Briigg. Brem. Abhandl. 1876, p. 80. Hab. Island of Sanghir. This well-marked race of Pt. melanocephalus differs, both in size and colour of plumage, so much that, more than any of the other styles, it deserves a separate name. The colour of the throat is of a deeper yellow ; and both abdomen and crissum are orange; and this colour runs up nearly to the breast instead of being confined to the short under tail-coverts and crissum. It is much larger than any of the other races. Male. Head and neck pearly white. Occiput and back of neck jet-black. Throat orange-yellow. Abdomen and crissum bright orange; long feathers of the under tail-coverts rich carmine. Entire rest of plumage bright yellowish green. Primaries and secondaries margined on their outer webs, near the tips, with lemon-yellow. First primary gradually narrowed towards tip. Bill black, tipped with yellow. Feet very dark red. Total length 10 inches, wing 5£, tail 3f, culmen f. Female. Entirely green. Feathers of the abdomen tipped with yellow. Some feathers of the under tail-coverts tipped with yellow, others with carmine. Bill black. Feet dark red. 38. PTILOPUS PORPHYREUS. Columba porphyrea, Temm. Pl. Col. 106 (1824) ; Knip & Prev.
